ROLLING-PIIN.

SPECIFICATION forming part of Letters Patent No. 643,780, dated February20, 1900.

Application filed June 21,1899.

To aZZ whom it may concern:

Be it known that I, GLAEENoE LESTER PITOHER, a citizen of the UnitedStates, residing at New York, (Long Island City,) in the countyof Queensand State of New York,have invented certain new and useful Improvementsin Rolling-Pins; and I do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to the figures of referencemarked thereon, which form a part of this specification.

My invention relates to rolling-pins; and its object is to provide meansfor reducing v the friction incident to the use of a rollingpin to theminimum.

The construction of the improvement will be fully described hereinafterand its novel features defined in the appended claims.

In the accompanying drawings, which form a part of this specification,Figure 1 is a view in perspective of a rolling-pin embodying myinvention, and Fig. 2 is a longitudinal seetional view of the same.

The reference-numeral 1 designates a roller formed with a central bore2, extending throughout the length of the roller, and with circular endrecesses 3, concentric with the bore. Within each of the end recesses 3is secured a cup-bearing 4, having a cone-surface 5 and formed withcentral openings, through which extends a shaft 6. This shaft projectsbeyond the ends of the roller 1 to support the handles of the device,and the ends of said shaft are reduced circumferentially andscrew-threaded for the purpose hereinafter explained. The shaft 6 isalso screw-threaded at the points 7 for the attachment of bearing-cones8, which latter'have cone-surfaces cooperating with the surfaces SerialNo- 721,865. (No model.)

5 to form a trackway for antifriction-balls 9. The bearing-cones 8 areformed with integral squared extensionslO, which facilitate theiradjustment.

11 and 12 designate the handles of the device comprising cylinders boredto fit the ends of the shaft and secured by caps 13, which are centrallybored and internally threaded to engage the threaded ends of the shaft.The caps are held in place by screws 14, which pass through openings inthe caps and into the ends of the handles.

It will be apparent from the drawings that the roller 1 will freelyrevolve in use without revolving the handles, and, further, that theantifriction devices greatly reduce the labor of rolling dough.

I claim- 1. A rolling-pin comprising a roller formed with a centrallongitudinal'bore, and end recesses concentric with said bore;antifrictionrollers supported within said recesses; a shaft extendingthrough the roller and projecting from the ends thereof; and handlesfixed to the ends of the shaft.

2. A rolling-pin comprising a roller formed with a central longitudinalbore, and end recesses concentric with said bore; cup-bearings securedwithin the recesses; a shaft extending through the roller; bearing-coneson said shaft; antifriction rollers supported within the recesses andbetween the cup-bearings and cones, handles on the ends of the shaft;and caps for securing the handles to the shaft.

In testimony whereof I afiiix my signature in presence of two witnesses.

CLARENCE LESTER PITCHER.
